Sets locations and sizes of floating point bit fields
Procedure:
H5T_SET_FIELDS (dtype_id, spos, epos, esize, mpos, msize)
Signature:
herr_t H5Tset_fields( hid_t dtype_id, size_t spos, size_t epos, size_t esize, size_t mpos, size_t msize )
SUBROUTINE h5tset_fields_f(type_id, spos, epos, esize, mpos, msize, hdferr)
IMPLICIT NONE
INTEGER(HID_T), INTENT(IN) :: type_id ! Datatype identifier
INTEGER(SIZE_T), INTENT(IN) :: spos ! sign bit-position
INTEGER(SIZE_T), INTENT(IN) :: epos ! exponent bit-position
INTEGER(SIZE_T), INTENT(IN) :: esize ! size of exponent in bits
INTEGER(SIZE_T), INTENT(IN) :: mpos ! mantissa bit-position
INTEGER(SIZE_T), INTENT(IN) :: msize ! size of mantissa in bits
INTEGER, INTENT(OUT) :: hdferr ! Error code
END SUBROUTINE h5tset_fields_f
Parameters:
hid_t dtype_id | IN: Identifier of datatype to set |
size_t spos | IN: Sign position, i.e., the bit offset of the floating-point sign bit |
size_t epos | IN: Exponent bit position |
size_t esize | IN: Size of exponent in bits |
size_t mpos | IN: Mantissa bit position |
size_t msize | IN: Size of mantissa in bits |
Description:
H5T_SET_FIELDS sets the locations and sizes of the various floating-point bit fields. The field positions are bit positions in the significant region of the datatype. Bits are numbered with the least significant bit number zero.
Fields are not allowed to extend beyond the number of bits of precision, nor are they allowed to overlap with one another.
Returns:
Returns a non-negative value if successful; otherwise returns a negative value.
